Yor   post has no data  You need to pass the form data  You can use serialize   to post the form data  Try this      post-btn   click function          post  process php       reg-form   serialize    function data           alert data

Get the value of your textboxes using val   and store them in a variable  Pass those values through   post  In using the   Post Submit button you can actually remove the form    lt script gt       username       username   val         password       password   val             post-btn   click function                      post  process php     username username  password password    function data               alert data                        lt  script gt

You have to select and send the form data as well       post-btn   click function                  post  process php       reg-form   serialize    function data            alert data                 Take a look at the documentation for the jQuery serialize method  which encodes the data from the form fields into a data-string to be sent to the server
